The speeds of three molecule are 3v , 4v and 5v find their root mean square speed |
|
Answer» t mean square SPEED (rms speed) is defined as the square root of the mean of squares of the individual speed of the molecules. Mathematically expressed as,VRMS=c21+c22+c23+...c2nn−−−−−−−−−√Vrms=c12+c22+c32+...cn2nwhere cici is the speed of individual molecules and nn is the number of molecules.Now, coming to the question:Vrms=(3V)2+(4V)2+(5V)23−−−−−−−−−−−−√=52√3V |
